Answer:

-2

Step-by-step explanation:

- 5x + 8 = 18

Take + 8 to the right hand side, it turns negative i.e -8

-5x = 18 - 8

-5x = 10

Divide both sides by the coefficient of x which is -5

-5x/5 = 10/-5

x = -2

Plot on graph.

Answer:

Axis of symmetry: x=-2

Maximum point: (-2,8)

Step-by-step explanation:

The given function is $h(x)=-\frac{1}{2}x^2-2x+6$ .

We can complete the square to reveal the axis of symmetry and the vertex.

We factor to get:

$h(x)=-\frac{1}{2}(x^2+4x)+6$

We add the zero pairs and obtain a perfect square:

$h(x)=-\frac{1}{2}(x^2+4x+4-4)+6$

$h(x)=-\frac{1}{2}(x^2+4x+4)+2+6$

$h(x)=-\frac{1}{2}(x+2)^2+8$

The function is now in the form $h(x)=a(x-h)^2+k$ , where V(h,k) =(-2,8) is the vertex.
